During the 1970 gubernatorial race, Democrat Cecil Andrus made saving Castle Peak from mining a key issue in his campaign.
The mountain is the highest peak in the White Cloud Mountains in central Idaho.
Years later, Republican Congressman Mike Simpson revived an effort to get the area around the range protected with help from Andrus.
The Boulder White Clouds wilderness was created in 2015, protecting 275,000 acres.
Now, Simpson wants to rename the area for Andrus, who died in August. The congressman introduced a bill to do so in the House Committee on Natural Resources this week.
